We've purchased the 42 and 72 inch version of this vanity.  First thing is Beachcrest Home obviously takes pride in their packaging.  They spend an extra dollar to encase the whole unit in thick styrofoam and brace in between the top and the shelves below, then another brace to to the bottom.  Second thing is they have an excellent QC department.   Both units were perfect, no flaws of any kind, doors and drawers fit square, and the quartz top is flawless.  One other thing worth mentioning is the communication from Wayfair is top notch.  You receive updates every step of the way.  5 star product and service.
